Another Cool Day, another 8K

cool day, air temperture: -1∘C, asphalt tempertaure: -3∘C.
Windy.
Started out feeling cold, hands tucked into my sleeves. I warmed up after 2 kilometers pulled out my hands. the rest of the run was totally routine.
I am still amazed that my feet warm up to the point where the road doesn't feel cold. I have full sensation in my feet, why can't I feel the cold in the road? As soon as I stop running (has to stop and get the mail) the cold road is there.
